IMPROVED MACmE FOR SEPARATING- AND CONCENTRATING MAGNETIC AND OTHER ORES.

Schedule referred to in these Letters Patent and making part of the same.

To all whom it may cqrwern:

Be it known that 1,1-Enwxnn L. SEYMOUR, of the new and improved Machine for Separating and Conthis ings, gives a full and clear description,

Figure 1 shows a longitudinal vertical section of one form of my machine, and

' Figure 2, a. plan view of the same.

wheel and rotating brushes, (but for which, may be s'ubstituted'other arrangements and devices,) for clear- Like letters of reference indicate like parts in the difierent figures. v

The most brief manner of setting forth the nature A is a horizontal Wheel, say of some hard wood, in

projecting through it, one or more circular rows of horse-shoe magnets, 13.

This wheel; while the machine is in action forseparating magnetic'ores, 's kept in constant rotation by motions, and the power to enable the machine to per-. formits functions, as will be readily understood, and

O is an endless apron, of any material that will'pfesent a tolerably smooth surface, and that will not greatly vary in its tautness, (as an apron or broad belt,) by ordinary changes of temperature or fair use, and is distended over proper rollers, and likewise kept contact withthe poles of the magnets B.

The ore, in a granulated state, is fed into a hopper, D, from which it is delivered upon the'endless apron C. The rear wall of." the lower end of D has attached escape of the granulated ore rearward.

To regulate the rapidity of the feed from the hopper to the endless apron, is an adjustable gate-a common device.

As the granulated or pulverized ore'is carried forparticle s, and carry them off from the others, and then, to break the adhesion of such particles to and separate them from the magnets, the latter, in the form of the machine here shown, come in contact with stationary i rotating brushes, E E, on opposite sides of wheel A,

(see figs. 2, 4, and 5,) and are detached, falling into proper conduits to receive them, and convey'them .to proper receptacles till wanted.

To prevent the incidental mechanical adhesion of any non-magnetic particles of ore, to the magnets, I, for one plan, atfix a spring-hammer or hammers, F, (see fig. 1,) under which the bows of the magnets pass, and dropping from one to the other, as thewheel rotates, is designed to jar off any such particles'as' last referred to.

The ore, after passi belt 0, and falls at 0 into a closed chamber, G, (see fig. 1,) which may be, say, of twenty'orthirty inches depth transversely.

slots, z 2:, extending a ross it, (such slots, slits, or orifices being adjustable in vertical width, by movable slides or gates, if necessary,).and such slits or long, exits forbiastsof'airfrom a small chamber or flue, H, to which air is supplied from a reservoir, into which it is continually forced, and mod- The wall of this cmamber next to c has horizontal erately compressed, by any proper means. of my invention will be to proceed at once to the detailed description.

Such reservoir is to be supplied with an escapevalve, or other device, to' keep the pressure of the contained air within certain limits, as desired, according to the ore being treated,

A plurality of blast-chambers and reservoirs may be employed, but I consider this useless.

As the thin sheet of ore, mixed with different impurities, and of differing coarseness and specific gravity of granules, falls at c, the jets of air issuing horizontally from the long apertures 2, project and separate the particles of difi'erent characters. The heavier, falling'upon the inclined sides of the nearest bridges i, descend through the passages or spaces between them to their own special receptacles or conduits i. The particles next heavier will fall upon the inclines of the bridges or sheds further off, and in like manner descend into conduits leading to other receptacles. Particles of lighter and baser quality will be projected further,-and fall on bridge i for example. But inasmuch as very fine particles of value might adhere to larger, lighter, and baser particles, I make .the transversely-inclined chute or conduit of 13 with two or more separate floors, (see w x, fig. 3,) which is a vertical transverse section through line 1 1 of fig. 2, as before stated, a: being perforated or made of siev ing, (sieve-cloth,) and x, a smooth plate. Y

Now, the impact of the coarser particlesjust referred to upon the bridge i would tend to jar ofi the major portion of the vfiner particles, and allow them to fall through the perforations of a; and go to their own'distinct receptacle, while the others would roll on and fall into another.

The number, size, and form of the bridges may of course be varied.

In treating ores unmixed with magnetic ores, A may remain inactive or be disconnected.-

g under A, is canied on by the sheet of such ore,

1. I claim in-an ore-separating machine, the plan of separating the granules of ore of different coarseness I and, specific gravities, by passing through a falling a series of air-jets of adjustable and uniform force, substantially in the manner described.

2.'I claim, in combination with the reservoir, from which such air-jets emanate, or'with some vessel or conduit communicating with said reservoir, the -application of any convenient device, by which the pressure of the-air in the latter; and the force and reach of the jets maybe adjusted and regulated according to the nature of the ore under treatment, substantially as and for the purpose explained.

' .3. I claim the combination of the horizontally-rotating magnets, and the endless carrier-belt G, or its equivalent, arranged and acting substantially in the manner and for the purpose described.

4. .I claim theuse of one or a series of long horizontal slits, z z, or any other kind of apertures that may be suitable, connecting with a single reservoir or with distinct reservoirs of compressed air, substantially as and for the purpose explained.

5. I claim the employment of the angular ore-separating b1idges-or sheds, substantially as and for the purpose set forth.

6. I claim the plan of making one or more of said bridges or conduits therefrom, or both perforated, for the-purpose explained.
